I've found that Arduino code can be written using AI. As a test case, I created the following in a Word document:

Given an Arduino mega and Arduino motor shield

Pins 23, 25, 27, 46, 47, 48 and 49 are inputs

If pin 25 is high, both motors are on

If pin 23 is high, the left motor is on forward and right motor is on reverse

If pin 27 is high the right motor is on forward and left motor is on reverse

If pin 46 or 47 or 48 or 49 is high, both motors are off

What is the Arduino code

I did a query using Google and received workable Arduino code--just had to copy it and paste it into the Arduino space. 

Beware that this is not perfect. When I did the same thing for the "find the trashcan, back up, then find the human," I received six pages of code. The code didn't work. For some reason, the second attempt assumed PWMA to use pin 10 instead of pin 3.
